The senior source familiar with Syrian government thinking said that the UAE role in persuading Assad should not be underestimated. A Syrian source close to the Gulf said the UAE had used its "soft power" on Assad and a Turkish official also said the UAE had played a part in persuading him. Moscow has tussled with Western states repeatedly at the Security Council over cross-border aid into Syria, arguing it violates Syria's sovereignty. Other Arab states, including U.S. allies, have also moved to normalise ties with Assad. The UAE official said there was an "urgent need to strengthen the Arab role in Syria".
